DETAILED DESCRIPTION OF THE DRAWINGS

One or more embodiments of the invention are described below. It should be noted that these and any other embodiments are exemplary and are intended to be illustrative of the invention rather than limiting. While the invention is widely applicable to different types of systems, it is impossible to include all of the possible embodiments and contexts of the invention in this disclosure. Upon reading this disclosure, many alternative embodiments of the present invention will be apparent to persons of ordinary skill in the art.

U.S. Published Patent Application No. 2023/0051350 (patent application Ser. No. 17/398,224, entitled METHODS AND APPARATUS FOR MULTI-PATH MESH NETWORK ENCRYPTION AND KEY GENERATION) filed Aug. 10, 2021 and co-owned with the present application is incorporated herein by reference in its entirety.

With the growth of the Internet of Things, existing devices are becoming networked in order to enable the monitoring, controlling, and communicating of the devices. Lighting and lighting systems are devices that are becoming networked in order to control power, color, and brightness. Currently, the method for incorporating a control system into an existing lighting system may be carried out by running wire or cable from a control device/panel to the lighting system. The running of the wire or cable may cost $10,000 per floor and may require days to accomplish. Additionally, the control device/panel may cost between $10,000 to $15,000. With such economics, the implementation of the Internet of Things to existing lighting systems has been slow in coming.

A method, apparatus, and system for monitoring, controlling, and communicating of devices may be described. The method, apparatus, and system may use a radio communication to power line communication bridge and networking system for the monitoring, controlling, and communicating of devices such as lighting systems. This method, apparatus, and system may not require the running of wire or cable and may be deployed in hours, not days, at a fraction of the cost of existing control systems. Since the apparatus may be used with any lighting fixture or lamp brand, the apparatus may be integrated into any existing lighting system.

FIG. 1 is a block diagram illustrating an apparatus for monitoring, controlling, and communicating in accordance with embodiments.

In embodiments, apparatus 100 may comprise at least one powernet control unit and at least one communication cube. The powernet control unit (PCU) 105 may comprise a PCU housing 107, a system bus 109, at least one processor 111, system memory 113, at least one non-transitory memory unit 115, a power port 117, an internal battery 119, a communication port 121, an inter-PCU/CC wireless module 123, and a GPS module 125, all of which may be directly or indirectly coupled to each other. The communication cube (CC) 106 may comprise a CC housing 127, a system bus 129, at least one processor 131, system memory 133, at least one non-transitory memory unit 135, an internal battery 137, an inter-PCU/CC wireless module 139, at least one control port 141, at least one control clamp 143, at least one monitor sensor 145, a RFID module 147, and a Bluetooth module 149, all of which may be directly or indirectly coupled to each other. In the installation of the apparatus, the PCU 105 may be mounted on the back of a flat electrical strike plate and may be powered by the internal battery 119 or by A/C power 151 through the power port 117 in embodiments. In embodiments, the communication port 121 may comprise at least one of a Wi-Fi radio, an Ethernet port, and a power line communication (PLC) bridge and may allow for the communication between powernet control units 105 and external control and monitoring devices such as mobile device 153, local server 155, and/or remote server 157. For Wi-Fi, PLC, and Ethernet, communication may be established through a communication gateway 159 such as a router/PLC/modem. Using a communication cube control web portal or a communication cube control app (PCU/CC dashboard application), at least one of the local servers 155 and the mobile device 153 may be used to communicate with the PCU 105 and the CC 106 through the communication gateway 159. Additionally, the communication gateway 159 may be connected to the Internet 161, thus making it possible for the remote server 157 and/or the mobile device 153, using a communication cube control web portal or a communication cube control app, to communicate with the PCU 105 and the CC 106. The PCU 105 may communicate with the CC 106 through the inter-PCU/CC wireless module 123 of the PCU 105 with the inter-PCU/CC wireless module 139 of the CC 106. The inter-PCU/CC wireless modules 123, 139 may comprise at least one of a Bluetooth radio, 6LoWPan radio, and ZigBee radio. Bluetooth, 6LoWPan, and ZigBee may encompass all past, current, and future versions of the wireless protocols. The powernet control units 105, which are connected to the PLC may be nodes, which, in turn, may be in communication with the communication cubes 106. Each PCU node may be capable of identifying the communication cubes 106 which are connected to it. This network of communication cubes 106 connected to PCU nodes which are connected via PLC may be referred to as a powernet.

In embodiments, the CC 106 may be mounted within a lighting fixture and may be powered by the internal battery 137 or by one of the at least one control clamp 143 spliced into the power line to the lighting fixture. The control clamp may be designed to splice the power line to a lighting fixture without having to shut down power to the lighting fixture or device. After splicing the power line, direct power to the lighting fixture may be removed and the CC 106 may now be capable of controlling the lighting fixture or device, thus enabling control for dimming, color, and other primary and secondary functions such as, but not limited to Li-Fi management and emergency controls. Since the control clamp 143 is tapped into the power line, the control clamp 143 may also be able to provide power to the CC 106 through the control port 141. The CC 106 may also comprise at least one monitor sensor 145 to monitor for occupancy in the area of the lighting fixture as well as the lighting fixture location and status.

In embodiments, the RFID module 147 and Bluetooth module 149 of the CC 106 may be used to establish a beacon. The RFID module 147 may be used to monitor the space around the lighting fixture or device for any RFID transmitters. In a hospital setting, the RFID transmitters may be mounted onto tables, drug carts, wheel chairs, etc. The CC 106 may then be able to keep track of the RFID transmitters in the vicinity of the lighting fixture. The Bluetooth module 149 may be used to continuously ping the area around the lighting fixture for any nearby Bluetooth enabled devices. The vast majority of phones and devices since 2006 may respond to this pinging, thus enabling the CC 106 to map and monitor the number of people that are carrying Bluetooth phones and devices that are in the vicinity of the lighting fixture. The processing of the RFID and Bluetooth monitoring may be handled locally by the at least one processor 131 of the CC 106. By having this map of people and things, if a patient is looking for a particular facility within the hospital, the path of least resistance (i.e. least congestion) for the patient to get to the particular facility may be determined from the data collected from RFID monitoring and Bluetooth pinging. This path may be transmitted to the patient who is running the hospital's mobile application on a Bluetooth enabled phone. In embodiments, the Bluetooth module 149 may be used to transmit offers, promotions, or other information to an individual with a Bluetooth enabled phone running a particular store or promotion mobile application. In such a scenario, if a customer is shopping at a grocery store and is running a store's mobile application on a Bluetooth enabled phone and the customer approaches the soft drink aisle, the CC 106 may be able to determine that the customer is in the soft drink aisle and may be able to present the customer offers and promotions for products that are also in the soft drink aisle. The CC 106 may present offers for products that are available since the CC 106 may use its RFID module 147 to detect for products labeled with RFID tags.

FIG. 2 is a block diagram illustrating an apparatus for monitoring, controlling, and communicating in accordance with embodiments.

In embodiments, apparatus 200 may comprise at least one powernet control communication cube 205. The powernet control communication cube (PCCC) 205 may comprise a housing 207, a system bus 209, at least one processor 211, system memory 213, at least one non-transitory memory unit 215, a power port 217, an internal battery 219, a communication port 221, at least one control port 223, at least one control clamp 225, at least one monitor sensor 227, a GPS module 229, an RFID module 231, and a Bluetooth module 233, all of which may be directly or indirectly coupled to each other.

In embodiments, the PCCC 205 may be mounted within a lighting fixture or on the back of a flat electrical strike plate and may be powered by the internal battery 219 or by using one of the control clamps 225 coupled to the power port 217 to tap into a power line. Alternatively, the power port 217 may draw its power internally from one of the control clamps 225 connected to the control port 223. The communication port 221 may comprise at least one of a Wi-Fi radio, a PLC bridge, an Ethernet port, ZigBee radio, 6LoWPan radio, and a Bluetooth radio and may allow for the communication between powernet control communication cubes 205 and external control and monitoring devices such as mobile device 235 and remote server 237. Bluetooth, 6LoWPan, and ZigBee may encompass all past, current, and future versions of the wireless protocols. For Wi-Fi, PLC, and Ethernet, communication may be established through a communication gateway 239 such as a router/PLC/modem. Using a PCCC control web portal or a PCCC control app (PCCC dashboard application), the mobile device 235 may be used to communicate with the PCCC 205 through the communication gateway 239. Additionally, the communication gateway 239 may be connected to the Internet 241, thus making it possible for at least one of the remote servers 237 and the mobile device 235, using a PCCC control web portal or a PCCC control app, to communicate with the PCCC 205. Using the Bluetooth radio of the communication port 221, the mobile device 235 may also be capable of communicating with the PCCC 205 through the communication port 221. The powernet control communication cubes 205 may also communicate with each other through the communication port 221 using the Bluetooth radio, 6LoWPan radio, and/or ZigBee radio. The powernet control communication cubes 205 which are connected to the PLC may be nodes which in turn may be in communication with the powernet control communication cubes 205 which may not be connected to the PLC. Each PCCC node may be capable of identifying the powernet control communication cubes 205 which may be connected to it. This network of powernet control communication cubes 205 connected to PCCC nodes which are connected via PLC may be referred to as a powernet. Lastly, the GPS module 229 may provide location data for the PCCC 205 and may allow for the traceability of the PCCC 205 in event of its theft.

In embodiments, the RFID module 231 and Bluetooth module 233 of the PCCC 205 may be used to establish a beacon. The RFID module 231 may be used to monitor the space around the lighting fixture or device for any RFID transmitters. In a hospital setting, the RFID transmitters may be mounted onto tables, drug carts, wheel chairs, etc. The PCCC 205 may then be able to keep track of the RFID transmitters in the vicinity of the lighting fixture. The Bluetooth module 233 may be used to continuously ping the area around the lighting fixture for any nearby Bluetooth enabled devices. The vast majority of phones and devices since 2006 will respond to this pinging, thus enabling the PCCC 205 to map and monitor the number of people that are carrying Bluetooth phones and devices that may be in the vicinity of the lighting fixture. The processing of the RFID and Bluetooth monitoring may be handled locally by the at least one processor 211 of the PCCC 205. By having this map of people and things, if a patient is looking for a particular facility within the hospital, the path of least resistance (i.e. least congestion) for the patient to get to the particular facility may be determined from the data collected from RFID monitoring and Bluetooth pinging. This path may be transmitted to the patient who is running the hospital's mobile application on a Bluetooth enabled phone. In embodiments, the Bluetooth 233 may be used to transmit offers, promotions, or other information to an individual with a Bluetooth enabled phone running a particular store or promotion mobile application. In such a scenario, if a customer is shopping at a grocery store and is running a store's mobile application on a Bluetooth enabled phone and the customer approaches the soft drink aisle, the PCCC 205 may be able to determine that the customer is in the soft drink aisle and may be able to present the customer offers and promotions for products that are also in the soft drink aisle. The PCCC 205 may present offers for products that are available since the PCCC 205 uses its RFID module 231 to detect for products labeled with RFID tags.

FIG. 3 is a block diagram illustrating an apparatus for monitoring, controlling, and communicating in accordance with embodiments.

In embodiments, apparatus 300 may comprise at least one powernet control communication cube 305.

In embodiments, the PCCC 305 may be mounted within a lighting fixture or on the back of a flat electrical strike plate and may be powered by the internal battery 319 or by using one of the control clamps 325 coupled to the power port 317 to tap into a power line. Alternatively, the power port 317 may draw its power internally from one of the control clamps 325 connected to the control port 323. The communication port 321 may comprise at least one of a Wi-Fi radio, a PLC bridge, an Ethernet port, ZigBee radio, 6LoWPan radio, and a Bluetooth radio and may allow for the communication between powernet control communication cubes 305 and external control and monitoring devices such as at least one of a mobile device 327 and a remote server 329. Bluetooth, 6LoWPan, and ZigBee may encompass all past, current, and future versions of the wireless protocols. For Wi-Fi, PLC, and Ethernet, communication may be established through a communication gateway 331 such as a router/PLC/modem. Using a PCCC control web portal or a PCCC control app (PCCC dashboard application), the mobile device 327 may be used to communicate with the PCCC 305 through the communication gateway 331. Additionally, the communication gateway 331 may be connected to the Internet 333, thus making it possible for at least one of the remote servers 329 and the mobile device 327, using a PCCC control web portal or a PCCC control app, to communicate with the PCCC 305. Using the Bluetooth radio of the communication port 321, the mobile device 327 may also be capable of communicating with the PCCC 305 through the communication port 321. The powernet control communication cubes 305 may also communicate with each other through the communication port 321 using the Bluetooth radio, 6LoWPan radio, and/or ZigBee radio. The powernet control communication cubes 305 which may be connected to the PLC may be nodes which in turn may be in communication with the powernet control communication cubes which are not connected to the PLC. Each PCCC node may be capable of identifying the powernet control communication cubes 305 which may be connected to it. This network of powernet control communication cubes 305 connected to PCCC nodes which are connected via PLC may be referred to as a powernet.

In embodiments, the PCCC 305 may be used to control a single lamp, a single fixture, and/or a series of fixtures. For such an embodiment, the PCCC 305 may be mounted within the lighting fixture and may be powered by the internal battery 319 or by one of the at least one control clamp 325 spliced into the power line to the lighting fixture. The control clamp 325 may be designed to splice the power line to a lighting fixture without having to shut down power to the lighting fixture or device. After splicing the power line, direct power to the lighting fixture may be removed and the PCCC 305 may now be capable of controlling the lighting fixture, thus enabling control for dimming, color, and other primary and secondary functions such as, but not limited to Li-Fi management and emergency controls. Since the control clamp is tapped into the power line, the control clamp may also be able to provide power to the PCCC 305 through the power port 317. This embodiment was similarly disclosed in FIG. 2 , except that in this embodiment, the components not required for controlling a lighting system, (the at least one monitor sensor, the GPS, the RFID, and Bluetooth) have been eliminated.

In embodiments, the components for communication through the communication gateway may be separated from the components for communication between the powernet control communication cubes 305. In such an embodiment, the powernet control unit may comprise at least one of the Wi-Fi radio, the Ethernet port, and the power line communication (PLC) bridge and the communication cube 305 may comprise at least one of a Bluetooth radio, 6LoWPan radio, and ZigBee radio, as was similarly disclosed in FIG. 1 , except that in this embodiment, the components not required for controlling a lighting system (the at least one monitor sensor, the GPS, the RFID, and Bluetooth) have been eliminated.

Embodiments described herein relate to a computer storage product with at least one non-transitory memory unit having instructions or computer code thereon for performing various computer-implemented operations. The at least one memory unit are non-transitory in the sense that they do not include transitory propagating signals per se (e.g., a propagating electromagnetic wave carrying information on a transmission medium such as space or a cable). The at least one memory unit and computer code (also can be referred to as code) may be those designed and constructed for the specific purpose or purposes. Examples of at least one memory unit include, but are not limited to: magnetic storage media such as hard disks, floppy disks, and magnetic tape; optical storage media such as Compact Disc/Digital Video Discs (CD/DVDs), Compact Disc-Read Only Memories (CD-ROMs), and holographic devices; magneto-optical storage media such as optical disks; carrier wave signal processing modules; and hardware devices that are specially configured to store and execute program code, such as Application-Specific Integrated Circuits (ASICs), Programmable Logic Devices (PLDs), Read-Only Memory (ROM), and Random-Access Memory (RAM) devices.

Examples of computer code include, but are not limited to, micro-code or micro-instructions, machine instructions, such as produced by a compiler, code used to produce a web service, and files containing higher-level instructions that are executed by a computer using an interpreter. For example, embodiments may be implemented using Java, C++, Python, C, or other programming languages (e.g., object-oriented programming languages) and development tools. Additional examples of computer code include, but are not limited to, control signals, encrypted code, database code, and compressed code.

As discussed, a single multifunction communications cube (MCC) may have multiple means or subsystems for receiving and transmitting digital information. It will be understood that a multifunction communication cube (MCC) may include all, or a subset, of the same or similar components, features, and functionality of apparatus 100, apparatus 200, and apparatus 300 described in detail elsewhere in this application. The MCC may use its communications subsystems or inputs (Wi-Fi, ZigBee, Bluetooth, PCL, Ethernet, etc.) to generate a “digital impression” or “digital profile” including digital impression information of the devices in its environment. The digital impression may contain essentially all, or a subset of, signal information across all of the CC's detection means for each and every device that the MCC can detect. The digital impression information collected about different devices in the environment of the MCC may differ in relation to signal information available and collected by the CC. The MCC may monitor all of the inputs simultaneously, or in any suitable order to generate such a digital impression. Monitoring of inputs by the MCC may include monitoring all or a subset of communications subsystems of the CC. This digital impression may be limited only by the inherent limitations of the different input methodologies or input subsystems of the CC. In an embodiment, for example, the CC's ability to monitor devices via its PLC inputs may be limited to devices connected to an electrical circuit accessible to the CC, while the devices observable via the CC's Bluetooth and Wi-Fi inputs may be limited to the communication reception ranges determined by each device's Bluetooth antenna range and Wi-Fi antenna range. The signal information from all inputs available to the MCC may be aggregated to generate the digital impression. Multiple CCs with overlapping sensor ranges may have separate digital impressions that contain devices that overlap, or alternatively, may be aggregated together to create a single, more thorough or complete digital impression of the devices around the plurality of networked CCs. In an embodiment, for example, a first MCC and second MCC in communication, directly or indirectly via other intermediate CC's relaying communications information between the first MCC and second CC, may have combined, coordinated, or cooperative capability to identify, monitor, and interact with devices via PLC inputs connected to any electrical circuit accessible or connected to either the first MCC and the second CC, and further may have combined, coordinated or cooperative capability to identify, monitor and interact with the same or other devices via Bluetooth and Wi-Fi inputs within wireless communication range of both the first MCC and second CC. In such an embodiment, for example, digital impressions of each of a plurality of devices may include digital impression information obtained via PLC inputs, Bluetooth inputs, and Wi-Fi inputs, of each and every device observable, directly or indirectly, by the first MCC and second CC.

In an exemplary scenario, if a MCC is installed into a powerline circuit in a room with a Wi-Fi enabled smart TV that is connected to the same powerline circuit as the CC, a Bluetooth and Wi-Fi enabled cell phone sitting by itself on a desk in the next room over, and a ZigBee enabled smoke detector connected to a separate powerline circuit in the hall between the two rooms, the MCC may receive both a PLC signal and a Wi-Fi signal from the TV, both Wi-Fi and Bluetooth signals from the cell phone, and a ZigBee signal from the smoke detector. The digital impression generated by the MCC would comprise all of these signals together.

The CC's onboard processor may aggregate this sensor data in order to generate the digital impression of the CC's environment. The MCC may then use its processor and information contained on its onboard memory to identify digital signatures of the different devices constituting the digital impression. If the digital impression cannot be disambiguated to determine the unique signatures identifying the constituent devices, the MCC may use one or more of its communications pathways to transmit the digital impression to a remote server, which may have access to more data and processing capabilities than the CC's onboard hardware in order to disambiguate the digital impression and determine what devices are being sensed by the CC. Once the digital impression has been disambiguated and the unique devices sensed by the MCC are identified that information along with control information for those devices may be communicated from the remote server back to the MCC through a suitable communication network. The unique device information may comprise information such as the make and model of the device, and may further comprise control information including, but not limited to control signals compatible with the identified device through one or more communications means, and a hierarchy of what communications means are preferred for controlling said device. Whether or not the MCC can determine the devices constituting the digital impression through onboard processing versus offboard processing at a remote server may be a question of the CC's form factor and current hardware limitations.

Once the MCC has either determined the identity of the devices that it sensed in its digital impression, or has received such information from the remote server, the MCC may then use any of the output methods available to it to communicate with and control the unique devices whose signals were include in the CC's digital impression. The determination of what communication means should be used to control which unique device may be associated with the information used to identify of the unique devices, and may be determined when the unique devices are identified. This control and control preference information may be stored either on the CC's or on the remote server's memory. This selection of the means by which to control the devices may be limited to the manner in which the MCC can communicate with that particular device (it would not be helpful for the MCC to try to control a Wi-Fi enabled TV via Wi-Fi if either the MCC does not possess Wi-Fi functionality, or if the MCC is in only powerline communication with the TV).

Continuing with the example provided above, once the MCC has formed a digital impression of its environment, including the PLC signature of the TV, the Wi-Fi signatures of the TV and the smartphone, the Bluetooth signature of the smartphone, and the ZigBee signature of the smoke detector, it may transmit this impression to a remote server, and receive back from the server information indicating the three devices and their control preferences. The stored device information indicates that the TV may be controlled via PLC, infra-red (IR), and Wi-Fi, but prefers to be controlled via IR or Wi-Fi; the smartphone prefers to be controlled by Bluetooth rather than Wi-Fi; and the smoke detector can be controlled by PLC or ZigBee and has no preference on which is better. In such a case, the MCC would control the TV via Wi-Fi as it is preferred over PLC and the MCC does not possess IR; the smartphone via Bluetooth as it is preferred over PLC; and the smoke detector via ZigBee as it is the only connection that the MCC has to that device.

In embodiments, the MCC may be limited to having fewer than all of the possible input and communications means. For example, one MCC may be configured for Ethernet and PLC communication only, while another MCC may be configured for Ethernet and Bluetooth communication only, while yet another MCC may be configured for wireless, Bluetooth, and PLC communication. Any permutation or combination of communication means may be provided for on any specific MCC without departing from the scope of this disclosure. Embodiments without the capability of at least one communications means may be termed a “limited CC”. Multiple differently limited CCs, for example, one that is limited to Bluetooth and PLC, and one limited to Bluetooth and Wi-Fi, may communicate together via their shared communication protocol. In such an example the Bluetooth and PLC limited MCC may relay its digital impression to a remote server by using its shared communication protocol (in this case Bluetooth) to relay information to the other CC, which may then transmit both its digital impression and the digital impression received from the other limited MCC to the remote server via Wi-Fi.

In embodiments, a single MCC may be configured to use any and all suitable communications means.

Multiple CCs may be networked together via suitable communications networks. Multiple CCs in a particular physical location may be considered a “node”. Multiple nodes may be connected together to form a network or MCC network. In embodiments, a single node may constitute a network or MCC network.

The CCs in a node may transmit and receive communications with one another in order to determine which of the CCs has the strongest connection to a communication network capable of transmitting information to a target device external to the node. The other CCs of the node may then relay information to the target device through the MCC with said strongest connection. The MCC through which the node's information is relayed may update in the event that the connection strength changes. This may allow all of the CCs in the node to be able to communicate with the remote device even if any particular MCC cannot directly communicate with said remote device. Furthermore, this relaying of information between networked CCs does not have to be direct, and may be indirect. For example, a first MCC may transmit information to a second CC, which may, in turn, transmit the information from the first MCC to a third CC, that may then transmit the information from the first MCC to a remote device. This ability to relay information through a series of networked CCs may also provide for a “gap jumping” ability, where an MCC that is not capable of transmitting directly to a remote device may relay information through one or a series of connected CCs until one of them is able to establish a connection to the remote device.

This relaying of information between networked CCs does not have to be direct, and may be indirect. In embodiments, a plurality of CCs constituting a node may be connected together in a mesh network configuration. Such a mesh network of CCs, for example, may relay information using either a flooding technique or a routing technique. To ensure all its paths' availability, the network may allow for continuous connections and should be able to reconfigure itself around broken paths, using self-healing algorithms. Self-healing allows a routing-based network to operate when a node breaks down or when a connection becomes unreliable. Utilizing such a mesh network configuration, a first MCC may transmit information to a second CC, which may in turn transmit the information from the first MCC to a third CC, that may then transmit the information from the first MCC to a remote device. This ability to relay information through a series of networked CCs may also provide for a “gap jumping” ability, where an MCC that is not capable of transmitting directly to a remote device may relay information through one or a series of connected CCs until one of them is able to establish a connection to the remote device.

FIG. 6 is a diagram illustrating a network environment 1500 for purposes of describing a self-healing network embodiment. This network environment 1500 may correspond to a node mentioned above. For purposes of example, let us assume that the network environment 1500 comprises a plurality of CCs 1501 a-1501 h in an office building that are interconnected in a mesh network configuration. Each CC may be connected to one or more networked electronic devices 1503, such as computers, printers, cellular telephones, alarm system nodes, Wi-Fi routers, security cameras, digital temperature sensors (i.e., thermometers) and other environmental sensors, servers, and any other type of networkable electronic devices that might typically be found in an office building. In order not to obfuscate the drawing and the ensuing discussion, FIG. 6 shows only four of the electronic devices, namely, a first computer 1503 a coupled to CC 1501 a, a second computer 1503 b coupled to CC 1501 b, a server 1503 c coupled to CC 1501 c, and a smart phone 1503 d coupled to CC 1501 d. Each CC 1501 is able to communicate with at least one other CC, and, in most cases, with multiple other CCs, as shown, thereby forming a mesh network through which the electronic devices 1503 (as well as the CCs 1501) can communicate with each other and exchange data as needed. Each line (or edge) between any two CCs represents a direct communication path between those two CCs (hereinafter sometimes referred to as a “link”). As previously discussed, the various links may be of different communication modes. For example, in FIG. 6 , the solid lines represent Digi 900 Mhz wireless communication links, the dot/dashed lines represent power line communication (PLC) links, the dashed lines represent Wi-Fi links, and the dotted lines represent Ethernet wired links.

Furthermore, as previously discussed, each CC 1501 may have more than one communication link with any other CC. For instance, CC 1501 a may have an Ethernet link, a Wi-Fi link, and a PLC link with CC 1501 b. However, again, for sake of not obfuscating the drawing, only one communication link per pair of CCs is assumed and shown in FIG. 6 . Each CC may have a unique MAC address per communication mode. Thus, a CC that, for example, has Wi-Fi 2.4 GHz capabilities, Wi-Fi 5.2 GHz capabilities, Ethernet capabilities, and PLC capabilities would have four MAC addresses.

In this example, the network environment 1500 also includes a gateway 1505 that connects the network environment to the outside world, e.g., to the Internet, so that the devices 1503 and CCs 1501 can communicate with resources outside of the network environment in the building.

In an example, if computer 1503 a needs to send data to a remote location outside of the network environment 1500, it would do so via the gateway 1505, which is a connection to outside world (e.g., the Internet). Thus, computer 1503 a transmits the data to CC 1501 a, which needs to get that data to the gateway 1505. However, CC 1501 a does not have a direct connection to the gateway 1505. Thus, it must send the data to gateway 1505 via one or more other CCs 1501 in the network environment. As can be seen in FIG. 6 , there are many options for transmitting the data from CC 1501 a to gateway 1505. Merely as a few examples, in one case, the data can be transmitted from CC 1501 a through CC 1501 b, CC 1501 c, CC 1501 d, and 1501 f to gateway 1505. This would comprise a total of five hops from the source CC 1501 a to the gateway 1505. Alternately, it could be transmitted from CC 1501 a through CC 1501 e, and CC 1501 f to gateway 1505. This route would comprise only three hops from source CC 1501 a to gateway 1505. Many other routes also are available. Also, in certain cases, the network environment may have two or more gateways that connect to the internet, thereby providing an even greater variety of routes through the network environment to any given remote destination (as it would likely have multiple potential routes through the network environment to each of the gateways).

A routing algorithm through the mesh network should be selected to optimize the use of the network resources. U.S. patent application Ser. No. 17/484,592 filed Sep. 24, 2021, entitled METHODS, SYSTEMS, AND APPARATUS FOR ROUTING DATA IN A SELF-HEALING NETWORK AND FOR SELF-HEALING OF A NETWORK, which is incorporated herein in its entirety by reference, discloses suitable routing algorithms for such a system. In an embodiment, a plurality of CCs may cooperate to identify and share digital impression information regarding network routers and network security devices, such as network security packet sniffers, of a secured network for evading detection by the secured network routers and network security devices while identifying, monitoring, interacting with, and controlling devices on the secured network. The plurality of CCs may establish and communicate over a separate mesh communications network, or over any other network accessible to the plurality of CCs. In embodiments, where the plurality of CCs may have developed and shared, or may have received from a remote server, digital impression information regarding network routers and network security devices at an established or acceptable confidence level, one or more of the plurality of CCs may communicate over a separate mesh network established between the plurality of CCs, and/or may communicate over the secured network according to protocols that are unidentifiable or undetectable by the secured network routers and network security devices so as to remain “dark” and undetected. In embodiments, one or more of the plurality of CCs may also communicate over the secured network according to protocols that are compatible, identifiable, or detectable by the secured network routers and network security devices so as to spoof or simulate other devices known to be on the network, or that might belong on the network, to misinform the secured network routers and network security devices regarding the security or unsecured status of the secured network, and/or also to misinform network security devices regarding operations and operating status of devices identifiable, or known, by the CCs. It will be understood that the term “devices” may include firmware and software associated with hardware devices or nodes.

In embodiments, CCs may automatically assign themselves identifiers. Automatic identification of the CCs may be performed, for example, in accordance with a 6LoPan protocol. A plurality of networked CCs may automatically share digital impression information for devices detectable by, or known to, any of the plurality of CCs, and automatically share instructions for monitoring, interacting with, and controlling such devices.

In embodiments, the manner in which the MCC may be able to control the devices on its circuit vary depending on the device. For power modulation where there may no digital management capability. For example, for incandescent light bulb or older TVs, the only options will be off/on dim up/dim down. Those “commands” are managed through increasing or decreasing the voltage and/or current being transmitted to the device being controlled through the powerline. The MCC may effectuate such a modulation of voltage and/or current through the use of a series of circuits, or through a series of resistors/transistors if analog. For other devices, which may be controlled wirelessly, the MCC may provide control signals to the device through a suitable wireless communication means (e.g. Wi-Fi, Bluetooth, IR, etc.) rather than through modulation of the waveform of the power line into which the device is connected. For example, The MCC may identify a smart TV through the power line and identify it as a TV, and may then implement a control profile identified as usable via Wi-Fi or IR. The preference of control methodology for the specific device may associated with the unique device once it is identified. The preferred control means may be limited by the communications capabilities of the MCC that is trying to control the device.

Generally, not all electrical circuits in a building are connected. Even circuits within the same breaker panel are often not directly connected. Whether it is for meeting code requirements, load limit restrictions, security, redundancy, reduction of single point failure, or convenience, multiple distinct electrical circuits are used. Addressing these hurdles when implementing a network is an additional advantage of the MCC over current technologies. Multiple CC's can be networked together to create a mesh network spanning large open areas. Multiple CC's can also be connected to communicate along that circuit over great distances and through physical barriers like floors, walls, and ceilings. These CCs may be able to communicate with one another through alternate compatible communications means or subsystems if one such means of communication is not available. For example, if two CCs both have Wi-Fi functionality and are within Wi-Fi range of one another, but are not connected to the same powerline circuit, the two CC's may communicate through the Wi-Fi network (or indirectly through the MCC mesh network) rather than communicating via PLC. Since all CCs in proximity are able to communicate as programmed (meeting designated network security requirements), either wirelessly, wired, or both, a network of CC's can “jump” significant distances between electrical circuits, through physical barriers like floors and walls where wireless signals would not otherwise penetrate via powerline, or through electromagnetic barriers, via a wireless and/or wired mesh network. It will be understood that electromagnetic barriers may include, for example, a Faraday cage electromagnetic barrier.

As shown in FIG. 7 , a multifunction communication cube (MCC) may be connected or spliced into an electrical circuit without interrupting the downstream power flow of the circuit through use of a specially designed clamp. Referring to FIG. 7 , clamp 1100 may be an insulated tube 1105 that has a single, non-conductive (glass, ceramic, etc.) blade 1110. In some embodiments, clamp 1100 may include a conductive blade 1115 that may be narrower at the top than at the bottom, and made of a conductive material (copper at minimum) and a contact pad 1130 connected to the top of the conductive blade via solder, wire etc. The contact pad 1130 allows for current to flow from the inside of the insulated tube 1105 to the outside of the insulated tube 1105. The contact pads 1130 have a wire connector 1125 that may transfer power from the insulated tube 1105 to an external device (not shown). It will be understood that this design accommodates a single wire 1120 conductor.

U.S. Pat. No. 11,102,115, which is incorporated herein by reference in its entirety, discloses additional methods, apparatus, and embodiments for connecting a communication cube into an electrical circuit without interrupting the downstream power flow.

Referring to FIG. 8 , in an embodiment disclosed subject matter includes method 800 for identification, communication, monitoring, and control of electronic devices at a site or node. Method 800 may include installing 805 a plurality of multifunction communication cubes (CC's) at the site or node. It will be understood that each multifunction communication cube (CC) may have a construction, features and functionality as described elsewhere in this application. A site may include, for example, at least one subject wired circuit, at least one subject wireless communication channel, or both, connected to at least one subject electronic device. Method 800 may include self-identifying 810 by each MCC via a self-identification protocol. A suitable self-identification protocol may be embodied in processor accessible code, such as software code. In an embodiment, a suitable self-identification protocol is 6LowPan. Method 800 may include pinging 815 by each MCC all sensory inputs, including available communications inputs, to identify all other CCs in the node. Method 800 may include identifying 820 by each MCC signal strength to an external target device such as, for example, a wireless network access point or wireless communications transceiver, for communication to a remote server over an external communications network such as, for example, the Internet. It will be understood that a suitable wireless communications transceiver may include a transceiver of a wireless mobile data network or cellular communications network. Method 800 may include identifying 820 signal strengths from each MCC to an external target device. Method 800 may include determining 825 whether each MCC having a relatively weaker signal strength to an external target device can see and enter into communications with another MCC having relatively strongest signal strength to an external target device. Method 800 may include direct routing 830 of information by all CCs in the node through an MCC identified as having the relatively strongest signal strength to an external target device. Method 800 may include indirect routing 835 of information by any CCs in the node to an intermediary MCC and from the intermediary MCC through an MCC identified as having the relatively strongest signal strength to an external target device. Method 800 may include receiving 840 information by an MCC identified as having the relatively strongest signal strength to an external target device, from other CCs in the node. Method 800 may include transmitting 845 information by the MCC identified as having the relatively strongest signal strength to an external target device, to said external target device. It will be understood that the particular MCC identified as having relatively strongest signal strength to an external target device may change from time to time as conditions at the site change, or as external target devices such as external wireless infrastructure changes. It will be understood that method 800 may be performed by any suitable system such as, for example, system 900 shown in FIG. 9 .

Referring to FIG. 9 , in an embodiment disclosed subject matter includes system 900 for identification, communication, monitoring, and control of electronic devices at a site. System 900 may include a first node 906 and second node 908 at the site. The first node 906 and second node 908 may be identical, except that each node may be connected to different infrastructure at the site and/or each node may include different sets or groups of multifunction communication cubes (MCC's). The first node 906 is exemplary and will be described in further detail. First node 906 may include a plurality of multifunction communication cubes (MCC's) (914, 916, 918, 920) at the site. It will be understood that each multifunction communication cube (914, 916, 918, 920) may include all, or a subset, of the same or similar components, features, and functionality of apparatus 100, apparatus 200, and apparatus 300 described in detail elsewhere in this application. In the particular embodiment shown in FIG. 9 , the multifunction communication cubes (MCC's) are more specifically characterized by reference to such devices including wireless communications subsystems (MCCW1, MCCW2), and other such devices including both wireless communications subsystems and wired or powerline connections (designated MCCW+P1, MCCW+P2). First node 906 may include, for example, multifunction communication cubes (MCC's designated MCCW+P1, MCCW+P2) connected to a subject wired circuit having at least one subject wired device (PDI, PD2) connected thereto. A subject circuit may be, for example, an electrical circuit of a building to provide power to electronic devices, or any other suitable circuit such as a wired Ethernet connection of such a building. As shown in FIG. 9 , each MCC may be connected to at least one conductor of the subject circuit via a clamp as described elsewhere and shown in FIG. 7 , or may be otherwise connected or installed in conductive relationship with at least one conductor or wire of the subject circuit. First node 906 may include, for example, multifunction communication cubes (MCC's designated MCCW1, MCCW2, MCCW+P1, MCCW+P2) each connected to subject wireless communication channels and providing wireless connections to each subject wireless electronic device (WDI, WD2) within wireless reception and transmission range of such multifunction communication cubes (MCC's designated MCCW1, MCCW2, MCCW+P1, MCCW+P2). A subject wireless communication channel may be, for example, a ZigBee, Wi-Fi or Bluetooth wireless communication channel or infrastructure associated with the building or structure at the site, associated with a network at the site, or associated with subject wireless electronic devices present at the site. Each MCC may ping over all available inputs (P1, P2) of the MCC to a subject wired circuit to subject wired devices (PDI, PD2) and to subject wireless communications channels to subject wireless devices (WDI, WD2). The plurality of multifunction communication cubes (MCC's designated MCCW1, MCCW2, MCCW+P1, MCCW+P2) each may also include suitable wireless communication subsystems, such as 6LoWPAN subsystems, providing wireless communication channels and enabling wireless connections with each other multifunction communication cube (MCC's designated MCCW1, MCCW2, MCCW+P1, MCCW+P2) within wireless reception and transmission range of such multifunction communication cubes (MCC's designated MCCW1, MCCW2, MCCW+P1, MCCW+P2). Each of the multifunction communication cubes (MCC's designated MCCW1, MCCW2, MCCW+P1, MCCW+P2) may receive device signal information, signal noise, and/or conflated device signals via available inputs of the MCC from the respective subject circuits and subject wireless communications channels. Each of the multifunction communication cubes (MCC's designated MCCW1, MCCW2, MCCW+P1, MCCW+P2) may aggregate by an MCC local processor device signal information, signal noise and/or conflated device signals recorded from each of the inputs of the CC, to generate an aggregated digital impression or multidimensional digital impression information including recorded signal noise and recorded wireless communications information. Each of the multifunction communication cubes (MCC's designated MCCW1, MCCW2, MCCW+P1, MCCW+P2) may perform disambiguation determining or analyzing of constituent unique device waveforms in recorded device signal information, signal noise and/or conflated device signals, by the local processor of the MCC comparing the recorded device signal information, signal noise and/or conflated device signals with samples of known unique device waveforms of known devices and/or devices previously or contemporaneously identified at the site, which are stored in MCC memory and/or stored in a local database of the MCC or any MCC in communication with the subject MCC at the site. Each of the multifunction communication cubes (MCC's designated MCCW1, MCCW2, MCCW+P1, MCCW+P2) may perform local identifying of devices from the aggregated digital impression information by the MCC. Each of the multifunction communication cubes (MCC's designated MCCW1, MCCW2, MCCW+P1, MCCW+P2) may perform transmitting of aggregated digital impression information from the MCC to a remote device, such as a remote server 925, via a connection to an external communications network. It will be understood that, for example, the remote server 925 may be accessed over the Internet. Remote server 925 may perform remote disambiguation determining or analyzing of aggregated digital impression or multidimensional digital impression information including recorded signal noise and recorded wireless communications information to identify constituent unique device waveforms in recorded device signal information, signal noise and/or conflated device signals, and to identify constituent device wireless communications properties or wireless constituent device identification information, by a remote processor of the remote server 925 comparing the recorded device signal information, signal noise and/or conflated device signals with samples of known unique device waveforms of known devices and/or devices previously or contemporaneously identified at the site, and comparing recorded wireless communications information with known wireless communications information or properties of known devices or device types to identify constituent device wireless communications properties or wireless constituent device unique identification information, which are stored in memory (not shown) associated with the remote server and/or stored in a remote database (not shown). It will be understood that one suitable database of known devices and device waveforms and identification information may be, for example, the MIT Project Dilon signal fingerprint database. Remote server 925 may perform analyzing to identify devices connected to a subject circuit or capable of communicating over a subject wireless communication channel or wireless infrastructure at the site, by identifying unique device waveforms of known devices that produce same, or identifying device wireless communications information or properties of known devices, from the remote database. Remote server 925 may transmit identification information of devices from the remote server over a suitable communications network to the multifunction communication cubes (MCC's designated MCCW1, MCCW2, MCCW+P1, MCCW+P2). Each of the multifunction communication cubes (MCC's designated MCCW1, MCCW2, MCCW+P1, MCCW+P2) may perform associating of device control pathways, such as command signals, with each identified device connected to a subject circuit connected to a multifunction communication cube (MCC's designated MCCW1, MCCW2, MCCW+P1, MCCW+P2) or visible over a wireless communications connection or channel to a multifunction communication cubes (MCC's designated MCCW1, MCCW2, MCCW+P1, MCCW+P2), by a processor of the same. It will be understood that command signals of devices may be obtained from local memory of the multifunction communication cubes (MCC's designated MCCW1, MCCW2, MCCW+P1, MCCW+P2). Multifunction communication cubes (MCC's designated MCCW1, MCCW2, MCCW+P1, MCCW+P2) by the local MCC processor may generate or transmit command signals or control signals associated with identified devices connected to the subject circuit, and/or over a wireless communications connection or channel, to interact with and control aspects of such identified devices. It will be understood that, in some embodiments, command signals or control signals may be communicated to such identified devices over a wireless connection to an identified device, via a suitable wireless subsystem of the multifunction communication cubes (MCC's designated MCCW1, MCCW2, MCCW+P1, MCCW+P2). It will be understood that the first node 906 and second node 908 may communicate and share information regarding wired electronic devices (PD1, PD2) and wireless devices (WD1, WD2).

FIG. 10 illustrates a system 1000 including network 1004 having a first node 1006 and second node 1008. Each of the first node 1006 and second node 1008 include a respective single multifunction communication cube (MCC) (1016, 1026) having wireless and wired communications capabilities and subsystems. System 1000 may be otherwise identical, or substantially similar, to system 900 illustrated in FIG. 9 .

Routine Data Over Medium and High Voltage Power Lines

In embodiments, any of the communication cubes disclosed herein above, including any of the apparatus shown in FIGS. 1-3 , may be adapted to provide communication over power lines that carry voltages greater than the 120 volt or 240 volt power typically found in households and offices. These include what are known as medium and/or high voltage power lines. High voltage power lines refer to those types of power lines that are commonly used to transmit power from large scale power plants to cities, and typically carry about 100,000 to about 200,000 volts or higher. Medium voltage power lines refer to those types of power lines that are commonly used to transmit power between sub-stations in different cities, and typically carry about 1,000 volts to about 69,000 volts or higher.

When electrical power is transported over long distances, it is commonly transported at such high voltages to reduce the resistance of the physical medium (i.e., the wires). It is stepped down by a transformer to a lower, more useful voltage for local distribution. For instance, power may be transported from a power plant to a city at 100,000 to 200,000 volts over hundreds of miles with relatively little loss. Transformer stations in the city may step that voltage down by about an order of magnitude to transmit to other substations in the same or nearby cities. Other transformer stations in the city may step down the voltage to lower levels for transport within the city, and then yet other transformer stations will step the voltage down further for distribution into households, offices, etc.

Typically, electrical power is transmitted as an alternating current (AC) at a relatively low frequency. For instance, in the United States, almost all electrical power, including, high voltage transmission lines, medium voltage transmission lines, and local transmission lines, carry AC current at 60 Hz. Transformers are electrical devices that take an input current at one voltage and output a current at a different voltage. A step-down transformer takes an input current at a relatively higher voltage and outputs an output current at a relatively lower voltage. A step-up transformer takes an input current at a relatively lower voltage and outputs an output current at a relatively higher voltage. A transformer essentially comprises two inductor coils of different sizes positioned adjacent to each other with a generally nonconductive medium (e.g., air) between them. Generally, inductors are poor transmitters of high frequency electrical signals, but are excellent transmitters of low frequency electrical signals (where direct current (DC) essentially may be considered zero frequency current). In power distribution, most transformers are step-down transformers since, in power transmission, voltage is almost always stepped down incrementally from the power plant to a city substation, to a more local substation, and ultimately to a final destination, such as a household, hospital, office, manufacturing plant, etc. Since most power distribution systems in the world transmit power at about 50 Hz or 60 Hz, transformers used in power distribution are generally designed to pass current at frequencies up to at least 60 Hz. However, such transformers generally cannot pass through electrical signals at frequencies much higher than that, such as the frequencies at which data is typically transmitted. For instance, currently, Wi-Fi signals are generally modulated at approximately either 2.4 GHz or 5 GHz. (It will be understood by those of skill in the related arts that, although the term frequency is used in this discussion, any given Wi-Fi or other radio transmission typically consumes a frequency range, rather than one specific frequency, and, thus, the term frequency should be understood as including frequency ranges). Hence, generally, data at any reasonable frequency at which data might typically be transmitted (e.g., at least 1 KHz) cannot pass through a power line transformer. Thus, data transmitted on a power line at higher frequencies cannot make it through a transformer station.

In accordance with an embodiment, in order to transmit data over power lines that include high voltage and medium voltage transformers, provision is made to intercept the data on the power line on the upstream side of any transformer and place it back on the power line on the downstream side of the transformer.

FIG. 13A is a diagram illustrating a power distribution system comprising a 138 kilovolt (kV) high voltage line 1910 that runs between a power generation plant station 1901 and a substation 1903 in a nearby city (e.g., 60 miles away). For purposes of this discussion a substation may be considered to be a node of the power distribution system at which electrical current may be tapped off and distributed to one or more other nodes, such as other stations or substations, and/or stepped up or down in voltage (using a transformer). A substation also is a location at which data signals may be placed onto the power transmission lines and/or at which data signals on the power line may be received. Of course, many other functions may be performed at a substation, such as monitoring of the power lines, etc.

Substation 1903 may tap off and step down some of the power for further distribution within the city. FIG. 13A shows one such tap, namely, a 13.8 kV line 1912 to another substation 1905 that is, e.g., 3 miles away from substation 1903. Typically, there may be several other taps to other substations, etc., but FIG. 13A show only one other substation and transmission line (1905, 1912, respectively) in order not to obfuscate the drawing.

A computing device, such as a personal computer (PC) 1921 is located at power station 1901 and it is desired to place data from PC 1921 onto the high voltage power line 1910 for transmission to substation 1905 via substation 1903. According to an embodiment, the PC is coupled to a network node 1923, such as any of the aforementioned communication cubes of FIGS. 1-3 . In addition to the components illustrated in any of FIGS. 1-3 , network node 1923 further includes a separate port and interface for coupling to a high voltage line, such as line 1910.

Using the communication cube 200 of FIG. 2 as an example, FIG. 13B shows a modified communication cube 200′ in accordance with the present embodiment. Only blocks 221 and 239 are modified relative to the device illustrated by FIG. 2 . Particularly, an additional communication port for high voltage (HV) PLC is added to communication port block 221 and a corresponding gateway for high voltage (HV) power line is added to communication gateway block 239. The HV PLC communication port and the HV gateway may be identical to the original PLC communication port and gateway from FIG. 2 , respectively (labelled as low voltage PLC communication port and low voltage gateway in FIG. 13B in order to distinguish from the high voltage communication port and gateway, respectively). Similar modifications may be implemented in the communication cubes of FIGS. 1 and 3 to adapt them in the same manner.

Returning to FIG. 13A, data may be coupled from PC 1921 onto power line 1910 by transmitting the data from the PC 1921 to the network node 1923. Network node 1923 then forwards the data to a power line communication module (PLCM) 1925. PLCM 1925 is a transceiver for placing the data signals onto the power line (and/or receiving data signals from the power line). For purposes of the present discussion, it is being used as a transmitter and will be discussed as such. It may be a radio transmitter with the antenna output port connected to the power line (through a coupling capacitor voltage transformer (CCVT) as discussed below) instead of an antenna insofar as the power line will accept the data signals just as well as an antenna. The data signals will travel down the power line rather than through the air with no or minimal actual wireless signal radiation from the power line to the air. The transmitter 1925 may, for instance, comprise a 100 watt high frequency transceiver. PLCM 1925 couples to the high voltage power line 1910 through a CCVT 1931. A CCVT is commonly used in power transmission for coupling data onto a power line. It has a capacitance that is high enough that it cannot pass electrical signals at low frequency, e.g., the 60 Hz frequency of the power on the high voltage power line, but can pass signals of higher frequency, e.g., the data signals from PC 1921 and network node 1923. Accordingly, CCVT 1931 acts as a filter that passes the data signals from PLCM 1925 onto the high voltage power line 1910, but prevents any of the high voltage signal on line 1910 from feeding into the PLCM 1925, network node 1923, or PC 1921, which components are not capable of handling high voltages and would be damaged by such high voltage signals.

In addition, a wave trap 1933 is located on the power line upstream of the CCVT, wherein upstream in this context means in the direction opposite the direction in which the data signals are desired to travel and downstream means in the direction in which the data signals are desired to travel. A wave trap is a resonant circuit that prevents the higher frequency data signal from passing through it by presenting a high reactance to it. However, it allows the power signal, which is at a much lower frequency (e.g., 60 Hz) through by presenting a low reactance to low frequency signals. The wave trap causes substantially all of the energy of the data signal to travel only in the desired direction on the power line (i.e., toward substation 1905) while allowing the power signal to pass through it substantially unimpeded. In the absence of the wave trap 1933, half of the energy of the data signal would travel in the opposite direction on the high voltage power line and be wasted energy. Thus, most of the power of the data signal travels toward destination substation 1905, rather than merely half of it.

In addition, a high voltage transformer 1935 likely would be present at the power station for transforming the high voltage on the power line 1910 to another voltage for purposes related to power transmission and use at the station. Since, as previously described, the data cannot pass through the high voltage transformer because the inductive values of transformers commonly used on power lines will filter out any portion of the frequency above a relatively low cut-off frequency threshold (usually anything above about 100 Hz), the CCVT 1931 and wave trap 1933 should be positioned on the downstream side of the transformer 1935.

Since the data signal cannot pass through a high or medium voltage transformer, at substation 1903, another CCVT 1941 is coupled to the power line 1910 before any transformer at that location. As previously discussed, CCVT 1941 allows the data signal to pass through, but blocks the lower frequency (e.g., 60 Hz) high voltage power from passing through, thereby protecting the equipment on the other side of the CCVT from the high voltage on the power line 1910. Thus, the data is extracted from the power line 1910 by CCVT 1941 and passed to a receiver 1926. Again, receiver 1926 may be a transceiver like transceiver 1925 in power station 1902, but is being used as a receiver in this instant. Receiver 1926 forwards the data to a network node 1927, which may be identical to previously-described network node 1923.

Meanwhile, the high voltage, low frequency power signal continues down the power line 1910 through another wave trap 1943 (which blocks any remaining energy of the high frequency data signal from passing through). On the other side of the wave trap, the power signal may be tapped off by one or more transformers 1945, 1955 for use in lower voltage power transmission and usage purposes. For instance, transformer 1945 may step down the voltage to 4 kV for local distribution in the city (not shown). Similarly, transformer 1955 also may receive the original power signal at 138 kV and step it down by a factor of ten to 13.8 kV for transmission over a medium voltage power line 1912 to substation 1905.

As previously mentioned, the data that was placed on the high voltage power line 1910 is intended for substation 1905, not this substation 1903. Accordingly, the data is not processed or otherwise used at substation 1903, but rather needs to be placed back on power line 1910 downstream of the transformers 1945 and 1955 for further transmission down to substation 1905. Accordingly, network node 1927 transmits the data to another network node 1928 (e.g., via a local communication network of which nodes 1927 and 1928 are a part). Network node 1928 forwards the data to a PLCM 1929, which may be identical in all practical respects to PLCM 1925 in power station 1901.

PLCM sends the signal to another CCVT 1951 to couple the data onto power line 1912. Again, a wave trap 1953 is positioned on the power line 1912 on the upstream side of the CCVT. Furthermore, for the same reasons discussed in connection with station 1901, the wave trap 1953 and CCVT 1951 are positioned on the downstream side of the high (or medium) power transformer 1955.

Accordingly, the data has passed through substation 1903 without being lost in the high voltage transformers, e.g., 1945, 1955.

The data signal and the power signal travel down power line 1912 to substation 1905, where they encounter, in order, another CCVT 1961, another wave trap 1963 and another transformer 1965. Consistent with earlier discussion, CCVT 1961 extracts the data signal from the power line 1912 and lets the medium voltage power signal pass through down the power line through wave trap 1963 and to power transformer 1965. Power transformer steps down the voltage from 13.8 kV to, for instance, 240 volts for use in powering equipment at substation 1905.

Meanwhile the data signal is passed from CCVT to another receiver 1971, which may be similar to receiver 1926 in substation 1903. Receiver 1971 passes the data to network node 1973, which may be similar to aforementioned network nodes 1923, 1927, and 1928. Since substation 1905 is the desired destination for the data, network node 1973 forwards the data to another computing device at substation 1905, such as another PC 1979.

Thus, the data generated at station 1901 has traveled through high and medium voltage power lines 1910 and 1912 and through an intermediate substation 1903 intact for use at substation 1905 and with no disruption to the power transmission down those lines.

Although not specifically discussed above, it should be understood that data also may be transmitted in the other direction between any of stations/substations 1901, 1903, and 1905. In particular, for instance, wave traps 1943 and 1963 do not serve a significant function in the above-described example in which the data signal that is being transmitted in the left to right direction in FIG. 13A (from station 1901 to substation 1905 through substation 1903) because most, if not all, of the energy of the data signal has already been extracted from the power line before it reaches those wave traps. However, if data were being transmitted in the opposite direction (e.g., from substation 1905 to station 1901 through substation 1903), then wave traps 1943 and 1963 would serve the significant function of directing all of the data signal energy in the proper direction (but wave traps 1953 and 1933 would not be serving a significant function in that scenario since most, if not all, of the data signal energy has already been removed from the line before reaching the wave traps 1953 and 1933).
